	Commit message (Collapse)	Author	Age
*	Add LevelDB player database (#9982)	luk3yx	2020-06-12
|
*	Update manpage (#8169)	Paul Ouellette	2019-02-04
|
*	Add command line option to load password from file (#7832)	Kevin Abrams	2018-12-18
|
*	Rename 'subgame' to 'game'	paramat	2018-03-13
|
*	Add server side ncurses terminal	est31	2015-11-06
| | | | | | | | | | | | | | | | | | | | | | | |	This adds a chat console the server owner can use for administration or to talk with players. It runs in its own thread, which makes the user interface immune to the server's lag, behaving just like a client, except timeout. As it uses the same console code as the f10 console, things like nick completion or a scroll buffer basically come for free. The terminal itself is written in a general way so that adding a client version later on is just about implementing an interface. Fatal errors are printed after the console exists and the ncurses terminal buffer gets cleaned up with endwin(), so that the error still remains visible. The server owner can chose their username their entered text will have in chat and where players can send PMs to. Once the username is secured with a password to prevent anybody to take over the server, the owner can execute admin tasks over the console. This change includes a contribution by @kahrl who has improved ncurses library detection.
*	Clean up and tweak build system	ShadowNinja	2015-03-27
| | | | | | | | | | | | | | | |	* Combine client and server man pages. * Update unit test options and available databases in man page. * Add `--worldname` to man page. * Fix a bunch of places where `"Minetest"` was used directly instead of `PROJECT_NAME`. * Disable server build by default on all operating systems. * Make `ENABLE_FREETYPE` not fail if FreeType isn't found. * Enable LevelDB, Redis, and FreeType detection by default. * Remove the `VERSION_PATCH_ORIG` hack. * Add option to search for and use system JSONCPP. * Remove broken LuaJIT version detection. * Rename `DISABLE_LUAJIT` to `ENABLE_LUAJIT`. * Rename `minetest_*` variables in `version.{h,cpp}` to `g_*`. * Clean up style of CMake files.
*	Fix hyphen used as minus sign	Markus Koschany	2015-01-20
|
*	Search for subgames using $MINETEST_SUBGAME_PATH.	David Thompson	2014-10-22
|
*	Add --version option	Kahrl	2013-09-28
|
*	Add --migrate to manpages and update manpage dates	Kahrl	2013-09-10
|
*	Replace c55.me links	Kahrl	2013-06-03
|
*	Add --videomodes option to show available video modes	Kahrl	2013-05-09
|
*	Fix hypen used as minus sign (manpages), fix spelling error (server.cpp)	Ilya Zhuravlev	2012-12-17
|
*	Add output levels --info and --trace (--verbose is now more verbose)	Perttu Ahola	2012-03-22
|
*	Update --gameid to manpages	Perttu Ahola	2012-03-11
|
